摘　　要：植物保卫细胞是一类特化的具有运动能力的表皮细胞,成对出现,两个细胞之间的空隙即为气孔。气孔是植物与外界环境进行气体交换的场所,控制水分蒸腾和CO_(2)的吸入,是植物生命活动的重要保证。为了适应不同的生长环境条件,植物的气孔密度和气孔分布会发生适应性改变,以维持植物生长和生存之间的最佳平衡。气孔发育受植物内部和外部环境信号协同调控。近年来,环境因子参与气孔谱系细胞命运决定和气孔发育调控的研究取得了显著进展。本论文综述了光、CO_(2)、水分、温度和相对空气湿度(RH)等环境因子对气孔发育调控的最新研究进展,旨在深入解析植物适应环境变化的调控机制,为培育水资源高效利用型植物提供参考和启发。Guard cells are a specialized type of epidermal cell;they appear in pairs,and the gap between the two cells forms the stomata.Stomata serve as sites for gas exchange between plants and the external environment,controlling water transpiration and the intake of CO_(2).To adapt to different environmental conditions,plants undergo adaptive changes in stomatal density and distribution to maintain the optimal balance for plant growth and survival.Stomatal development is regulated by intrinsic and extrinsic cues.In recent years,significant progress has been made in understanding the regulatory mechanisms of environmental factors on stomatal development.This paper reviews the latest research progress on the regulation of stomatal development by environmental factors such as light,CO_(2),water,temperature,and relative humidity.The aim is to provide references and insights for a deeper understanding of the regulatory mechanisms underlying plant adaptation to environmental changes and the cultivation of plants with efficient water resource utilization.
